BoP Lab / Michelin Raceway Road Atlanta
FE2 vs SM vs SRF vs FF pace at Michelin Raceway Road Atlanta
Lap times across years say as much about the weather as the class. % of FE2 is each class's best lap as a share of FE2's on the same day, so the conditions drop out: 100% is level, less is quicker, and a move in it is the class getting faster or slower against the field.
Quickest here: FE2 1:23.054 Paul Schneider, Super Tour Mar 2022 race · SM 1:41.798 Danny Steyn, Super Tour Mar 2021 qualifying · FF 1:30.677 Nicholas d'Orlando, Super Tour Mar 2021 race

About this data
Best is the class's fastest lap in that event's qualifying or race sessions, with the driver who set it, how many cars set a time that session and how close the top five were; a best from fewer than three cars is greyed. With two or more classes, "vs" is the gap of each class's best to the first class's at the same event. "% of FE2" is the class's best as a share of FE2's best at the same event (100% is level, less is quicker): weather and track condition move every class together, so this compares across years where the raw times do not. It still breaks when FE2's own field changes or one session was wet and another dry. Newest event first. The coloured figure under each value is the change from the previous event that has one (green is quicker, red slower). Whole laps only, so events with different sector layouts still compare. Weather and track condition are not accounted for.
